1 Claim.

strips in which the strip or shutter is hinged to the bottom` edge of adoor and is held in inoperative position whenlthe `door is open, and isautomatically moved into and held in operative positionwhen the doorisclosed.` u

The main `object of the invention is to provide a new and improvedweather-strip construction to eliminate the use of the raised floor sillor threshold in common use to` provide clearance forthe lower edges ofdoors in swinging over carpets and other floor coverings; I

A further object is to provide a weather-strip construction of this typein which the weather strip and its operating mechanism are concealed` inthe lower edge of thefdoor while the latter is in open position.

, Other objects of the invention will become apparent as the detaileddescription thereof proceeds;` I H i Inthe drawing:

Figure 1 is a fragmentary perspective View of the lower part of a doorillustrating the only part of the weather strip visible while the dooris in open position;

Figure 2 is a fragmentary section of the weather Strip mechanism takenlengthwise through the lower ends of the Stiles and the bottom rail ofthe door;

Figure 3 is a fragmentary transverse section taken on the line 3 3 ofFigure 2;

Figure 4 is a section similar to Figure 3, but showing the stripoperating mechanism in a different position; and

Figure 5 is a fragmentary, vertical section taken transversely of thestrip and its pivot support in the positions occupied thereb-y while thedoor is open.

As shown in the drawing, the door 6 is hinged at one of its edges to thestile I of a door frame. The lower edge 3 of the door is shown inFigures 2, 3 and 4 as spaced away from the surface of the iioor 9 at adistancenecessary to secure clearance for the bottom edge of the door inswinging over carpets or other.` iioor coverings. Usually, thisclearance space would be occupied by a threshold which this invention isintended to eliminate. The lower edge of the` door is provided with agroove It; and the lower ends I of the outer edges of the stiles II andI2 of the door are countersunk to receive the hanger plates I3 and I4,respectively. These hanger plates, when in operative position, are flushwith the said outer edges of the respective stile II and I2` and aresecured` in position by means of the (Cl. -67) This invention relates tothat class of weather a screws I5 with their lower ends flush with thebottom of the groove I0.

` The hangers I3 tnd Ill are formed in pairs having apertured lugs I6and Il projecting downwardly from the lower ends of the hangers to 5 rodI8, a sheet metal strip`2ll is bentaround the ll).`

rody I3 for the greater part of its periphery and is then extended onopposite sides of the strip` I9. to form the clamping plates 2l` and 22which may be suitably secured to the strip I9 by rivets or otherSuitable securing means 23. ing plates andstrip form a shutter forsealing the lower ends of outside or inside doors against Wind, rain,snow or dust.

As shown in Figure 2, the clamping strips 2i and 22 and the strip I9 arerecessed to a depth 20 equal tothe thickness of the hanger platev It topermit the shutter to extend across the `stop shoulder formed by therabbet `of the door jamb 'I` at the hinged side of the door. At thestriking side of the door, the clamping strips 2| and 22 25 are cut awayto form a' recess 24 around the downwardly projecting lug I6 on thehanger plate I3. This recess 24 is extended inwardly a suiicientdistance to receive the trip camv 25. 'Ihis means that the recess in theshutter at 30 the striking edge of the door has a depth equal to thecombined thicknesses of the hanger plate I3 and the trip cam 25.

The trip cam 25 is larger in diameter than the diameter of the rod I3,and is provided with `a radial slot 26 tting snugly over the three`thicknesses of material formed by the weather strip I9 and clampingplates 2I and 22. 'Directly above the trip cam 25 and back` of thehanger plate I3, the edge of the striking stile II of the doo-r isprovided with a recess 27 into which projects a spring abutment 28formed integral with or suitably secured to a stud 29 pivoted in thehanger plate I3. The abutment 23 is bored transversely of its pivot axisto receive slidably the upper end of a pin 3B, provided near its lowerend, with aange 3I adapted to form a support for the lower end of `acompression spring 32, the upper end of which contacts with the 5abutment 28.

Belowthe flange` 3I, the pin 3D is ground or shaped to a chisel edgeseated in a notch 33` formed in the upper part of the trip cam 25. Thelower part of the trip cam 25 is provided 55 The clarnp- 151 35gContinued movement of the door inwardly 00 f surface of the floor 9 andsuitably secured thereto by means of the screw 40. The trip stud 31 isadapted to be adjusted vertically in the plate 39 and locked in adjustedposition by means of a lock nut 4I.

The door is shown in Figures 2 and 3 in its closed position and with theshutter I9 inoperative Contact with the floor 9. 4In Figure 4, the

door is shown in position whereV the trip cam has been operated by thetrip stud as the door is swung outwardly from closed position to movethe shutter I9 upwardly into concealed position in the groove I0.Continued outwardmovement of the door from the position shown in' Figure4 would leave the shutter I9 in the concealed position shown in Figure`4; and the shutter would be so held during the open position of thedoor by the pressure of the pin 30 against the trip cam in a directionlaterally displaced with `respect to the common pivot axis of the rod I8and cam.

Closing movement of the door yfrom open position to that shown in Figure4 will iirst` cause the projection 36 to slide over the 'flat top of thetrip stud 31 with the shoulder 35 moving into Contact with the sharpedge of the trip stud.

closing position causes the shoulder 35 to engage the'sharp edge of thetrip stud 31 and rocks the trip cam 25 about its pivot axis into theclosing position shown in Figures 2 and 3 of the drawing. While the dooris closed, the pressure of the spring 32 on the ange 3I of the pin 39maintains the trip cam in the position shown in Figures 2 and 3, theaxis oi the pin 30 being then laterally displaced to the opposite sideoi the pivot axis of the rod I8 from that occupied in the open-doorposition shown in Figure 4.

In order to avoid the necessity for using a very heavy construction ofpivot rod III/'and clamping means for securing the shutter I9 thereto,the groove I is formed so that the outer periphery of the sheet whichclamps the shutter I9 to the rod I8 is in slight frictional contact withthe square corner formed by the intersecting edges Y of the groove I0adjacent, the pivot rod I8. The

assembled shutter is flexible along its free edge and rigid lengthwise.When this shutter is in open-door position, itneed only be stiff enoughto support its own weight.A When the door is closed, a plane bisectingthe said corner angle is substantially coincided with the plane of theshutter I9 containing the pivot axis of the rod I8. 'Ihe intersectingsides of the said corner angle act as a V-block to hold the shutterrigid in all directions. This construction makes it possible to haveclose seating contact without binding and a minimum of friction.

The invention as disclosed herein is exceptionally simple, light andinexpensive. It is to be understood, however, that it is not to beconsidered as limited to the details of construction shown in thedrawing nor in any other way except as indicated by the scope of theclaim appended hereto.

What I claim` is:

In a weather strip for the` bottom edge of a door including a pivotedshutter, means for 0perating the shutter comprising a member secured tothe shutter, said member having a double faced peripheral cam, one faceradial to the laxis of the shutter and the other face perpendicular tothe rst face whereby said member canbe rocked in opposite directions inpassing a strike member secured to the floor, said member having adetent diametrically opposed to the cam and a spring impelled pivotedand slidable pin engaging said detent whereby the member is resilientlyheld at each extremeof the cam throw. v
